APPARATUS FOR REGULATING AND CONTROLLING THE EXIT OF GAS OR LIQUIDS.

SPECIFICATION formingpart of Letters Patent No. 396,078, dated January 15, 1889.

Application filed March 29, 1888. Serial No. 268,909. (No model.) I

To aZZ whom it may concern:

Be it known that I, CHARLES S. FORD, Sr., a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Regulating and Controlling the Flow of Gas or Liquids, which improvement is fully set forth in the following specification and accompanying drawings.

The invention consists of a tube with a post adapted to slide therein, the said post having a disk or diaphragm secured to one end thereof, a second disk or diaphragm having perforations, and a spring between said second disk and post, the lower end of the post having radial grooves aifording communication with the bore thereof, so as to permit the flow of the gas or liquid into said bore when the disk atthe lower end of the post is in contact with the tube.

It further consists of the combination of parts herein set forth, and claimed in the following specification, and illustrated in the accompanying drawings, in which Figure 1 represents a bottom view of the tube and post, and Fig. 2 represents a vertical section of the device.

Similar letters of reference indicate corresponding parts in the two figures.

A represents a tube or cylinder, adapted to be tightly fitted in the pipe or vessel A, through which the gas or liquid flows. Vithin the bore of the tube is the post B, hav'ing secured to it at its lower end the disk or diaphragm H, which has its under face concave, and is of a little less diameter than the bore of the pipe A, so that the gas can readily pass the disk on the sides thereof. The post B, as shown in the drawings, is angular in crosssection, so as to form the passages C from end to end of the tube. In the lower end of the tube are radial grooves D, communicating with the chamber J in the pipe A and the passages C.

Secured to the upper end of the post or stem B is a pin-piece, G, which extends beyond the sides of the bore of the tube into a recessed portion of the upper end of the said tube. Between this pin-piece G and the diaphragm F is located the coil-spring E, the upper end of which is within the recessed port-ion I on the under face of the diaphragm. The said diaphragm F has perforations K and is of such diameter as to tightly fit in the pipe A, so that the movement of the post B can be regulated, and also the amount of pressure necessary to force the disk H in contact with the lower end of the tube.

If desired, the pipe A and the tube A may be integral, the lower end of the pipe being screw-threaded, so as to be secured to a service-pipe when necessary. It will also be understood that the outlines of the passages C may be of any shape or conformation.

The operation of the device is simple and easily understood. The gas or liquid in the chamber J will exert a pressure upon the diaphragm H, and, passing around the same, will pass upward through the passages C, the amount of pressure as controlled by the tension of the spring E regulating the distance of the disk from the end of the tube, and so controlling the flow of gas or liquid. \Vhen the maximum of pressure is exerted on the disk II, it will be forced into contact with the lower end of the tube A, the radial grooves D, however, permitting the gas to reach the passages C, and thence through the perforations Kof the diaphragm F in a compara- 8o tively steadily though diminished flow.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A gas or liquid regulator consisting of a tube with grooves in its lower end, a post adapted to slide in the bore of said tube and having secured to its lower end a disk or diaphragm, a second disk with openings therein, and a spring between second diaphragm and post, the said post being fitted in said tube so as to form passages leading from end to end thereof, said parts being combined substantially as described.

2. A gas or liquid regulator consisting of a 5 tube having radial grooves in its lower edge, an angular post in the bore of said tube, forming passages between said post and tube, a perforated disk above said post, a spring between said disk and post, and a disk con- 10o heated to the lower and of said post, said parts being vomhineil sillisiiantially as (loscribed.
